JEST table and status change document OPL8

Hi Experts,

1. I created a prod order and released it and saved. went to AUFK and got the object number to pass in JEST table. System shows no values found.I was expecting a record for the same. do I need to do something to populate JEST table?

2. In OPL8 under implementation tab, there is something called status change documents. do I need to configure OCM to use these change documents? if the answer is no, then what is the difference between these change documents and OCM change documents?

thx in advance
